ABSTRACT:
An engine load parameter-calculating system for an internal combustion engine calculates an engine load parameter indicative of an amount of intake air drawn into the engine. The system determines a value of an opening area formed by a throttle valve and reflecting an amount of intake air, a reference value of the opening area in accordance with the rotational speed of the engine, and a value of the engine load parameter from the value of the opening area and the reference value of same. An engine control system calculates a basic control amount for controlling the engine by the use of the value of the engine load parameter.
